After reading the comments here and realizing that nothing is going to change about this because the central point of most of these arguments seems to be "If they don't force it on us then it won't ever develop into something we'll want to use", which is wrong entirely, it should be worth using before we have to use it, not the other way around, I will absolutely not be purchasing the Xbox One unless they choose not to make it mandatory and integral to the console's performance. I do not wish to use the Kinect, I do not like the features that it offers and would not like to use voice or motion controls. If they continue to force this onto us instead of making it worthy of our approval, then the choice for next generation consoles is quite clear.

Your argument entirely assumes that it already isn't something worth using. It's almost exactly comparable to when the ps one controllers first came out with the 2 joysticks (kinect for 360), where it was a neat feature, but nobody wanted to make a game dependent on them. The new kinect is like the ps 2 controllers, where the joysticks were a given and could thusly be developed around without worry, knowing it was a part of the system, not an optional addition. Maybe the features of a kinect don't appeal to you personally, and fair enough, but it likely already is something we'll want to use, because all the developers have known it's a feature, not an option.

It's a worthless feature, it's frivolous and pointless. This is only compounded by the fact that it's forced down our throats instead of being a sidebar item like it should be. The difference between your controller example and the Kinect is that the controller offered an obvious improvement upon older models, while the Kinect is just a novelty, a toy that is intriguing at best, but is not worthy of the attention that it's being given, and is certainly not worth being such an integral part of the Xbone's operations. There's no reason for it, other than pushing shitty technology on unwilling consumers.

It is not worth using. If you want those novelty features, buy a Wii, that's what it was made for.
